Iogen Corporation: "Cellulose ethanol and conventional (grain based) ethanol have identical molecules and can be easily integrated into the existing fuel distribution system. Grain ethanol has forged a path and created market acceptance that cellulose ethanol can follow and benefit from.

The difference between the two types of ethanol products is that conventional fuel ethanol is derived from grains such as corn and wheat. Cellulose ethanol is made from the non-food portion of renewable feedstocks such as cereal straws and corn stover.

Cellulose ethanol is a fully renewable, advanced biofuel that can be used in today's cars. It is one of the most cost effective ways to reduce greenhouse gas emissions and gasoline consumption use in road transport, and can deliver CO2 reduction benefits similar to improved vehicle efficiency."
